Śaṅkarācārya's commentary

Puruṣa is so called because He rests in the body, or because He is full. Than Him none is higher. He is attained by exclusive devotion, i.e., by jñāna or knowledge of the Self. All the created beings abide within the Puruṣa; for every effect rests within its cause; and by that Puruṣa the whole world is pervaded.
